First frag is either a pocilliopora or a stylophora, given the growth pattern and polyps.
Second frag is acropora sp. but no idea on individual species, hopefully it colours into a beauty for you
Third is, as mentioned above, a cyphastrea. The give away is the tissue patterning.
Fourth is definitely montipora
An encrusting type that will grow outwards as well, as you can tell by the little off-shots
Hope that helps
